“…[1]. Most recently, these materials have been the subject of investigations in the field of supercapacitors [2][3][4] and fuel cells [5,6], due to excellent capacitive properties. Depending on the application of interest, these oxide materials are usually composed of a mixture of a noble metal oxide, such as RuO 2 or IrO 2 , and an electrochemically inert, non-conductive or semiconductive oxide (TiO 2 , ZrO 2 , Ta 2 O 5 or Co 3 O 4 ) [1,[7][8][9], which stabilizes the coating and enhances the catalytic properties of the material.…”
